4. Given s and t, relations on Z, s = {(1,n) : n € Z} and t = {{n,1) : n E Z}, what are st and ts? Hint: Even when a relation involves infinite sets, you can often get insights into them by dråwing partial graphs.

Answer
4. Given s and t, relations on Z, s = {(1,n) : n E Z} and t = {(n, 1) : n E Z},
what are st and ts? Hint: Even when a relation involves infinite sets, you can
often get insights into them by dråwing partial graphs.
5. Let p be the relation on the power set, P(S), of a finite set S of cardinality
defined p by (A, B) e p iff An B = 0.
Consider the specific case n =
3, and determine the cardinality of the s
a.
p.
b. What is the cardinality of p for an arbitrary n? Express your answer in
terms of n. (Hint: There are three places that each element of S can go
